• Tokushima Line: Anabuki ⇄ Sadamitsu

Oshima Station opened on 25 March 1914 as one of several intermediate stops when Japanese Government Railways extended the Tokushima Main Line westwards to Awa-Ikeda. Freight handling ceased on 1 June 1970, parcel handling ended on 1 October 1972, and the station became unstaffed at the same time. JR Shikoku took over operation at the privatisation of Japanese National Railways on 1 April 1987, and the line was renamed the Tokushima Line on 1 June 1988. Limited kan'i itaku ticket-sales agency ended in December 2020. Today the station retains its tile-roofed wooden building set back from an island platform reached by a footbridge.

A 1973 amateur 8 mm short film titled "Oshima Station" documented the final days of staffed operations, capturing tablet exchanges with neighbouring stations and the now-vanished semaphore signals — it is preserved online by the Science Film Museum NPO.
